Removing Hard Water Stains from Pool Tiles

Hard water stains on your pool tiles can be embarrassing. These stains appear as a cloudy white residue caused from large amounts of minerals in the water, such as calcium and magnesium. The good news is that you can remove these stains with the chemicals you already use in your pool. If while cleaning the tiles you notice surface cracks or rust stains, contact a swimming pool contractor in Orange County for professional pool service.

Make Your Cleaning Mixture
To remove hard water stains, you will need to make a diluted muriatic acid mixture. Working outside and wearing rubber gloves and eye protection, slowly pour eight ounces of muriatic acid into a plastic bucket filled with one gallon of water. Stir the mixture slowly with an old plastic spoon. Any materials that come into contact with muriatic acid (measuring cup, spoon, plastic bucket) should be labeled for use in the future for muriatic acid only.

Spray and Scrub
Next, fill a plastic spray bottle with the muriatic acid and water mixture. Spray the pool tiles with the muriatic acid mixture and use a nonabrasive scouring pad to remove the hard water stains. Even though you use muriatic acid in your pool to help maintain the water's chemical balance, you are still working with a diluted acid and therefore should never attempt to clean the tiles from inside the pool.

Test Your Pool Water
After the pool tiles are clean, contact your local municipality to learn how to properly dispose of the acid. You should also contact a pool service provider in Orange County to test your pool water to determine the minerals present and recommend chemicals to avoid hard water stains in the future. A pool contractor can also tell you how to dispose of acid, as they should be familiar with your municipality's regulations.
